SOME TIPS ABOUT YOUR GLOBE’S
OPERATION
The lamp can be turned off with the square button. This will not turn off the
motor so your globe will continue to track the actual motion of the Earth.
The twilight strip on the lamp causes the line between day and night to be
slightly fuzzy, the way it is on the real Earth. The sunshade, which does not
move, causes the day and night effect by blocking the lamp. As your globe
turns, locations move into and out of the night side just as they do on Earth.
The line that divides the lit and unlit halves of the Earth is called the
terminator. When you are outside and see the Sun setting or rising, the
terminator is at your location. You can see the moon’s terminator when it is in
the sky.
Places that are on the same longitude line have the same solar time. For
example, find San Francisco and the longitude line closest to there. Look north
along the line until you come to Portland, Oregon. These are both at about
the same longitude. So if it is 8:00 am in San Francisco, it is 8:00 am in Portland.
The Time Ring is marked with hours and half hours. Estimating the correct
time to about 10 minutes is possible. Remember to correct for Daylight Savings
Time if it is kept in your area. Because the Earth’s speed in its orbit around the
Sun changes as the year goes by, the solar time on your globe may be off from
clock time by up to 10 to 15 minutes. This effect is called the Equation of Time.

WHAT WILL YOUR GLOBE SHOW?
The globe turns at the same rate that the actual Earth is turning. It will show the
day of the year, time of day, and which parts of the Earth are in day and night.
HANDLING AND CLEANING
Do not put the globe or the motor base in water. Clean all surfaces with a slightly
damp soft cloth. Paper towels may scratch the clear plastic.
When moving the globe, lift it only by holding the motor base. Do not lift it by
holding the globe since it could come apart where the hemispheres join, or might
damage the motor connections.
2. Rotate the globe support cup so that the
pointer with red tip points at today’s date.
3. Tighten the lock knob on the
support cup.
1. Loosen the lock knob on the
support cup.
5. To set the time as precisely as possible,
the longitude line nearest your location
should line up with the time on the
Time Ring. Once set, your globe should
only need minor adjustments every
couple of months, or when the power
to the globe is off.
ADJUSTMENTS
Setting the date and time
4. Find your current time on the
Time Ring.
With both hands, Lift the southern hemisphere of the
globe and turn the globe slowly so that your location
on Earth lines up with the current time on the Time Ring.
Note: Ensure both the locks
are perpendicular to the ring.
